Allow grep to recognize submodules and recursively search for patterns in each submodule. This is done by forking off a process to recursively call grep on each submodule. The top level --super-prefix option is used to pass a path to the submodule which can in turn be used to prepend to output or in pathspec matching logic. Recursion only occurs for submodules which have been initialized and checked out by the parent project. If a submodule hasn't been initialized and checked out it is simply skipped. In order to support the existing multi-threading infrastructure in grep, output from each child process is captured in a strbuf so that it can be later printed to the console in an ordered fashion. To limit the number of theads that are created, each child process has half the number of threads as its parents (minimum of 1), otherwise we potentailly have a fork-bomb.

Since 650c4492 (common-main: call git_extract_argv0_path(), 2016-07-01), the argv[0] that is seen in cmd_main() of individual programs is always the basename of the executable, as common-main strips off the full path. This can produce confusing results for git-daemon, which wants to re-exec itself. For instance, if the program was originally run as "/usr/lib/git/git-daemon", it will try just re-execing "git-daemon", which will find the first instance in $PATH. If git's exec-path has not been prepended to $PATH, we may find the git-daemon from a different version (or no git-daemon at all). Normally this isn't a problem. Git commands are run as "git daemon", the git wrapper puts the exec-path at the front of $PATH, and argv[0] is already "daemon" anyway. But running git-daemon via its full exec-path, while not really a recommended method, did work prior to 650c4492. Let's make it work again. The real goal of 650c4492 was not to munge argv[0], but to reliably set the argv0_path global. The only reason it munges at all is that one caller, the git.c wrapper, piggy-backed on that computation to find the command basename. Instead, let's leave argv[0] untouched in common-main, and have git.c do its own basename computation. While we're at it, let's drop the return value from git_extract_argv0_path(). It was only ever used in this one callsite, and its dual purposes is what led to this confusion in the first place. Note that by changing the interface, the compiler can confirm for us that there are no other callers storing the return value. But the compiler can't tell us whether any of the cmd_main() functions (besides git.c) were relying on the basename munging. However, we can observe that prior to 650c4492, no other cmd_main() functions did that munging, and no new cmd_main() functions have been introduced since then. So we can't be regressing any of those cases. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Add a super-prefix environment variable 'GIT_INTERNAL_SUPER_PREFIX' which can be used to specify a path from above a repository down to its root. When such a super-prefix is specified, the paths reported by Git are prefixed with it to make them relative to that directory "above". The paths given by the user on the command line (e.g. "git subcmd --output-file=path/to/a/file" and pathspecs) are taken relative to the directory "above" to match. The immediate use of this option is by commands which have a --recurse-submodule option in order to give context to submodules about how they were invoked. This option is currently only allowed for builtins which support a super-prefix.

Patch-id does not require a repository because it is just processing the incoming diff on stdin, but it may look at git config for keys like patchid.stable. Even though we do not setup_git_directory(), this works from the top-level of a repository because we blindly look at ".git/config" in this case. But as the included test demonstrates, it does not work from a subdirectory. We can fix it by using RUN_SETUP_GENTLY. We do not take any filenames from the user on the command line, so there's no need to adjust them via prefix_filename().

This is setup that should be done in every program for safety, but we never got around to adding it everywhere (so builtins benefited from the call in git.c, but any external commands did not). Putting it in the common main() gives us this safety everywhere. Note that the case in daemon.c is a little funny. We wait until we know whether we want to daemonize, and then either: - call daemonize(), which will close stdio and reopen it to /dev/null under the hood - sanitize_stdfds(), to fix up any odd cases But that is way too late; the point of sanitizing is to give us reliable descriptors on 0/1/2, and we will already have executed code, possibly called die(), etc. The sanitizing should be the very first thing that happens. With this patch, git-daemon will sanitize first, and can remove the call in the non-daemonize case. It does mean that daemonize() may just end up closing the descriptors we opened, but that's not a big deal (it's not wrong to do so, nor is it really less optimal than the case where our parent process redirected us from /dev/null ahead of time).

Every program which links against libgit.a must call this function, or risk hitting an assert() in system_path() that checks whether we have configured argv0_path (though only when RUNTIME_PREFIX is defined, so essentially only on Windows). Looking at the diff, you can see that putting it into the common main() saves us having to do it individually in each of the external commands. But what you can't see are the cases where we _should_ have been doing so, but weren't (e.g., git-credential-store, and all of the t/helper test programs). This has been an accident-waiting-to-happen for a long time, but wasn't triggered until recently because it involves one of those programs actually calling system_path(). That happened with git-credential-store in v2.8.0 with ae5f6776 (lazily load core.sharedrepository, 2016-03-11). The program: - takes a lock file, which... - opens a tempfile, which... - calls adjust_shared_perm to fix permissions, which... - lazy-loads the config (as of ae5f6776), which... - calls system_path() to find the location of /etc/gitconfig On systems with RUNTIME_PREFIX, this means credential-store reliably hits that assert() and cannot be used. We never noticed in the test suite, because we set GIT_CONFIG_NOSYSTEM there, which skips the system_path() lookup entirely. But if we were to tweak git_config() to find /etc/gitconfig even when we aren't going to open it, then the test suite shows multiple failures (for credential-store, and for some other test helpers). I didn't include that tweak here because it's way too specific to this particular call to be worth carrying around what is essentially dead code. The implementation is fairly straightforward, with one exception: there is exactly one caller (git.c) that actually cares about the result of the function, and not the side-effect of setting up argv0_path. We can accommodate that by simply replacing the value of argv[0] in the array we hand down to cmd_main(). Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

There are certain startup tasks that we expect every git process to do. In some cases this is just to improve the quality of the program (e.g., setting up gettext()). In others it is a requirement for using certain functions in libgit.a (e.g., system_path() expects that you have called git_extract_argv0_path()). Most commands are builtins and are covered by the git.c version of main(). However, there are still a few external commands that use their own main(). Each of these has to remember to include the correct startup sequence, and we are not always consistent. Rather than just fix the inconsistencies, let's make this harder to get wrong by providing a common main() that can run this standard startup. We basically have two options to do this: - the compat/mingw.h file already does something like this by adding a #define that replaces the definition of main with a wrapper that calls mingw_startup(). The upside is that the code in each program doesn't need to be changed at all; it's rewritten on the fly by the preprocessor. The downside is that it may make debugging of the startup sequence a bit more confusing, as the preprocessor is quietly inserting new code. - the builtin functions are all of the form cmd_foo(), and git.c's main() calls them. This is much more explicit, which may make things more obvious to somebody reading the code. It's also more flexible (because of course we have to figure out _which_ cmd_foo() to call). The downside is that each of the builtins must define cmd_foo(), instead of just main(). This patch chooses the latter option, preferring the more explicit approach, even though it is more invasive. We introduce a new file common-main.c, with the "real" main. It expects to call cmd_main() from whatever other objects it is linked against. We link common-main.o against anything that links against libgit.a, since we know that such programs will need to do this setup. Note that common-main.o can't actually go inside libgit.a, as the linker would not pick up its main() function automatically (it has no callers). The rest of the patch is just adjusting all of the various external programs (mostly in t/helper) to use cmd_main(). I've provided a global declaration for cmd_main(), which means that all of the programs also need to match its signature. In particular, many functions need to switch to "const char **" instead of "char **" for argv. This effect ripples out to a few other variables and functions, as well. This makes the patch even more invasive, but the end result is much better. We should be treating argv strings as const anyway, and now all programs conform to the same signature (which also matches the way builtins are defined).

Commit a60645f9 (setup: remember whether repository was found, 2010-08-05) introduced the startup_info structure, which records some parts of the setup_git_directory() process (notably, whether we actually found a repository or not). One of the uses of this data is for functions to behave appropriately based on whether we are in a repo. But the startup_info struct is just a pointer to storage provided by the main program, and the only program that sets it up is the git.c wrapper. Thus builtins have access to startup_info, but externally linked programs do not. Worse, library code which is accessible from both has to be careful about accessing startup_info. This can be used to trigger a die("BUG") via get_sha1(): $ git fast-import <<-\EOF tag foo from HEAD:./whatever EOF fatal: BUG: startup_info struct is not initialized. Obviously that's fairly nonsensical input to feed to fast-import, but we should never hit a die("BUG"). And there may be other ways to trigger it if other non-builtins resolve sha1s. So let's point the storage for startup_info to a static variable in setup.c, making it available to all users of the library code. We _could_ turn startup_info into a regular extern struct, but doing so would mean tweaking all of the existing use sites. So let's leave the pointer indirection in place. We can, however, drop any checks for NULL, as they will always be false (and likewise, we can drop the test covering this case, which was a rather artificial situation using one of the test-* programs).

There are many manual argv allocations that predate the argv_array API. Switching to that API brings a few advantages: 1. We no longer have to manually compute the correct final array size (so it's one less thing we can screw up). 2. In many cases we had to make a separate pass to count, then allocate, then fill in the array. Now we can do it in one pass, making the code shorter and easier to follow. 3. argv_array handles memory ownership for us, making it more obvious when things should be free()d and and when not. Most of these cases are pretty straightforward. In some, we switch from "run_command_v" to "run_command" which lets us directly use the argv_array embedded in "struct child_process".

The only code that cares about the value of the global variable saved_env_before_alias after the previous fix is handle_builtin() that turns into a glorified no-op when the variable is true, so the logic could safely be lifted to its caller, i.e. the caller can refrain from calling it when the variable is set. This variable tells us if save_env_before_alias() was called (with or without matching restore_env()), but the sole caller of the function, handle_alias(), always calls it as the first thing, so we can consider that the variable essentially keeps track of the fact that handle_alias() has ever been called. It turns out that handle_builtin() and handle_alias() are called only from one function in a way that the value of the variable matters, which is run_argv(), and it already keeps track of the fact that it already called handle_alias(). So we can simplify the whole thing by: - Change handle_builtin() to always make a direct call to the builtin implementation it finds, and make sure the caller refrains from calling it if handle_alias() has ever been called; - Remove saved_env_before_alias variable, and instead use the local "done_alias" variable maintained inside run_argv() to make the same decision.

When help.autocorrect is in effect, an attempt to auto-execute an uniquely corrected result of a misspelt alias will result in an irrelevant error message. The codepath that causes this calls save_env_before_alias() and restore_env() in handle_alias(), and that happens twice. A global variable orig_cwd is allocated to hold the return value of getcwd() in save_env_before_alias(), which is then used in restore_env() to go back to that directory and finally free(3)'d there. However, save_env_before_alias() is not prepared to be called twice. It returns early when it knows it has already been called, leaving orig_cwd undefined, which is then checked in the second call to restore_env(), and by that time, the memory that used to hold the contents of orig_cwd is either freed or reused to hold something else, and this is fed to chdir(2), causing it to fail. Even if it did not fail (i.e. reading of the already free'd piece of memory yielded a directory path that we can chdir(2) to), it then gets free(3)'d. Fix this by making sure save_env() does do the saving when called. While at it, add a minimal test for help.autocorrect facility. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The unfortunate commit d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR - 2015-06-26) exposes another problem, besides git-clone that's described in the previous commit. If GIT_WORK_TREE (or even GIT_DIR) is exported to an alias script, it may mislead git commands in the script where the repo is. Granted, most scripts work on the repo where the alias is summoned from. But nowhere do we forbid the script to visit another repository. The revert of d95138e6 in the previous commit is sufficient as a fix. However, to protect us from accidentally leaking GIT_* environment variables again, we restore certain sensitive env before calling the external script. GIT_PREFIX is let through because there's another setup side effect that we simply accepted so far: current working directory is moved. Maybe in future we can introduce a new alias format that guarantees no cwd move, then we can unexport GIT_PREFIX.

Commit d95138e6 [1] attempted to fix a .git file problem by setting GIT_WORK_TREE whenever GIT_DIR is set. It sounded harmless because we handle GIT_DIR and GIT_WORK_TREE side by side for most commands, with two exceptions: git-init and git-clone. "git clone" is not happy with d95138e6. This command ignores GIT_DIR but respects GIT_WORK_TREE [2] [3] which means it used to run fine from a hook, where GIT_DIR was set but GIT_WORK_TREE was not (*). With d95138e6, GIT_WORK_TREE is set all the time and git-clone interprets that as "I give you order to put the worktree here", usually against the user's intention. The solution in d95138e6 is reverted earlier, and instead we reuse the solution from c0562611 [4]. It fixed another setup-messed- up-by-alias by saving and restoring env and spawning a new process, but for git-clone and git-init only. Now we conclude that setup-messed-up-by-alias is always evil. So the env restoration is done for _all_ commands, including external ones, whenever aliases are involved. It fixes what d95138e6 tried to fix, without upsetting git-clone-inside-hooks. The test from d95138e6 remains to verify it's not broken by this. A new test is added to make sure git-clone-inside-hooks remains happy. (*) GIT_WORK_TREE was not set _most of the time_. In some cases GIT_WORK_TREE is set and git-clone will behave differently. The use of GIT_WORK_TREE to direct git-clone to put work tree elsewhere looks like a mistake because it causes surprises this way. But that's a separate story.

Most of the submodule operations work on a set of submodules. Calculating and using this set is usually done via: module_list "$@" | { while read mode sha1 stage sm_path do # the actual operation done } Currently the function `module_list` is implemented in the git-submodule.sh as a shell script wrapping a perl script. The rewrite is in C, such that it is faster and can later be easily adapted when other functions are rewritten in C. git-submodule.sh, similar to the builtin commands, will navigate to the top-most directory of the repository and keep the subdirectory as a variable. As the helper is called from within the git-submodule.sh script, we are already navigated to the root level, but the path arguments are still relative to the subdirectory we were in when calling git-submodule.sh. That's why there is a `--prefix` option pointing to an alternative path which to anchor relative path arguments.

For the purpose of rewriting git-am.sh into a C builtin, implement a skeletal builtin/am.c that redirects to $GIT_EXEC_PATH/git-am if the environment variable _GIT_USE_BUILTIN_AM is not defined. Since in the Makefile git-am.sh takes precedence over builtin/am.c, $GIT_EXEC_PATH/git-am will contain the shell script git-am.sh, and thus this allows us to fall back on the functional git-am.sh when running the test suite for tests that depend on a working git-am implementation. Since git-am.sh cannot handle any environment modifications by setup_git_directory(), "am" is declared with no setup flags in git.c. On the other hand, to re-implement git-am.sh in builtin/am.c, we need to run all the git dir and work tree setup logic that git.c typically does for us. As such, we work around this temporarily by copying the logic in git.c's run_builtin(), which is roughly: prefix = setup_git_directory(); trace_repo_setup(prefix); setup_work_tree(); This redirection should be removed when all the features of git-am.sh have been re-implemented in builtin/am.c.

For the purpose of rewriting git-pull.sh into a C builtin, implement a skeletal builtin/pull.c that redirects to $GIT_EXEC_PATH/git-pull.sh if the environment variable _GIT_USE_BUILTIN_PULL is not defined. This allows us to fall back on the functional git-pull.sh when running the test suite for tests that depend on a working git-pull implementation. This redirection should be removed when all the features of git-pull.sh have been re-implemented in builtin/pull.c.

'git -C ""' unhelpfully dies with error "Cannot change to ''", whereas the shell treats `cd ""' as a no-op. Taking the shell's behavior as a precedent, teach git to treat `-C ""' as a no-op, as well.

'was_alias' variable does not need to store it's value on each iteration in the loop; this variable gets assigned the result of run_argv() every time in the loop before being used. 'done_help' variable does not need to be static variable too if we move it out the loop.

This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: NAlex Henrie <alexhenrie24@gmail.com> Reviewed-by: NMatthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

"cache.h" and "commit.h" are already included via "builtin.h". We started to include "quote.h" at 575ba9d6 (GIT_TRACE: show which built-in/external commands are executed, 2006-06-25) that wanted to use sq_quote_print(). When 6ce4e61f (Trace into a file or an open fd and refactor tracing code., 2006-09-02) introduced trace.c API, the calls this file makes to sq_quote_print() were replaced by calls to trace_argv_printf() that are declared in "cache.h", which this file already includes. We should have stopped including "quote.h" in that commit, but forgot to do so. Signed-off-by: NAlexander Kuleshov <kuleshovmail@gmail.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

For normal use cases, it does not make sense for 'checkout' to work on a bare repository, without a worktree. But "checkout --to" is an exception because it _creates_ a new worktree. Allow this option to run on bare repositories. People who check out from a bare repository should remember that core.logallrefupdates is off by default and it should be turned back on. `--to` cannot do this automatically behind the user's back because some user may deliberately want no reflog. For people interested in repository setup/discovery code, is_bare_repository_cfg (aka "core.bare") is unchanged by this patch, which means 'true' by default for bare repos. Fortunately when we get the repo through a linked checkout, is_bare_repository_cfg is never used. So all is still good.

There was a redundant code for a builtin command retrieval in 'handle_builtin()' and 'is_builtin()'. Introduce a new function 'get_builtin()' and using it from both of these places to reduce the redundancy.

Blocked and ignored signals -- but not caught signals -- are inherited across exec. Some callers with sloppy signal-handling behavior can call git with SIGPIPE blocked or ignored, even non-deterministically. When SIGPIPE is blocked or ignored, several git commands can run indefinitely, ignoring EPIPE returns from write() calls, even when the process that called them has gone away. Our specific case involved a pipe of git diff-tree output to a script that reads a limited amount of diff data. In an ideal world, git would never be called with SIGPIPE blocked or ignored. But in the real world, several real potential callers, including Perl, Apache, and Unicorn, sometimes spawn subprocesses with SIGPIPE ignored. It is easier and more productive to harden git against this mistake than to clean it up in every potential parent process.
